Reinforcing ongoing rumors, Moore’s Law Is Dead has returned in a new video claiming that NVIDIA’s upcoming Lovelace-based flagship, the GeForce RTX 4090, will feature a relatively ridiculous TBP of 600 watts. This is a 150-watt increase over the specifications of green team’s current gaming champion, the GeForce RTX 3090 Ti, which finally released last month and is the first GPU to feature the new 12+4-pin 12VHPWR power connector.

RTX 4090 600w TBP Leak: Lovelace is CONFIRMED to be INSANE! (+ RX 6×50 XT Update) (Moore’s Law Is Dead)

Look, I just have to admit this despite hearing the top estimate was 600 watts and, and despite, you know, really respecting Igor a lot and knowing that he was saying and what he is planning to support up to that much I have to just admit that I have been thinking this whole time that there’s, it’s very unlikely, even if it’s possible, that NVIDIA actually hits the top of that upper estimate end.

Well, now I’m here to tell you they almost certainly will not hit 850 watts. But that’s right. The current references I can directly confirm to you today seems to be 600 watts total board power and that in fact the 4090 seems to likely be the first Lovelace card to launch not a midrange card, as far as I can tell.

Note that the 600-watt TBP claim is being applied to the reference design of NVIDIA’s upcoming flagship board, an indication that custom GeForce RTX 4090 graphics cards will draw even greater power due to higher clocks and more sophisticated cooling solutions. Moore’s Law Is Dead suggests that some of these might feature a TBP in the range of 700 watts.

  1. So lets see if I get this:
    1) You need to be insanely rich to buy one from a scalper or super lucky to get one of the five that are sold to a non-scalper.
    2) You will also need to be independently wealthy to pay the electric bill - or at least put on several more solar panels on the roof just to reduce the cost.

    At least in the winter I wont need to turn on my heater.
  2. I thought it was TDP, does TBP stand for thermobaric ?
    Might be 'Total Board Power', though I'm not sure on the 'T', that's usually 'Thermal'. Current aftermarket GPUs can easily pull 450W, and they can cool it pretty darn well too - so 600W isn't as much of a stretch as one would think.

    All of a sudden I see a possible use for the Lian Li O11 Dynamic's dual PSU mounts. One PSU for the graphics card, another for the rest of the system.
    I'm thinking my RM1000X might not be enough for one of these and the 12700K with a custom loop... but I do have plenty of spares laying around. Need to do a fan swap on one of the 850W TX units and it'd be good to go.
